Materialien

Beryllium und intermetallische Berylliumlegierungen (wie Be12Ti) werden als Neutronenvervielfacher-Materialien für zukünftige Kernfusionsreaktoren in Betracht gezogen. Diese Materialien sollen unvermeidliche Neutronenverluste durch Verdoppelung ihrer Anzahl mittels (n,2n)-Reaktionen ausgleichen. Die so zusätzlich gewonnenen Neutronen sind in der Lage zusätzliches Tritium zu erzeugen, das, zusammen mit Deuterium, als Brennstoff für die Fusionsreaktion verwendet wird und selbsterhaltende Brennstoffkreisläufe ermöglicht.

Eine breite Auswahl anderer Materialien wird ebenfalls in Betracht gezogen: 
•    Metalle in dichtester Kugelpackung (z.B. Beryllium, Zirkonium, Yttrium),
•    krz-Metalle (Eisen, nanostrukturierte ferritische Stähle, Vanadiumlegierungen und Wolfram),
•    kfz-Metalle (austenitische Stähle am Beispiel von -Fe),
•    intermetallische Verbindungen (Beryllide, Fe17Y2).

Diese verwandten Materialien sind nicht nur Kandidaten für fortgeschrittene Kern- und Fusionsreaktoranwendungen, sondern haben auch ein hohes Potenzial als Strukturwerkstoffe für konzentrierte Solarkraftwerke, Düsentriebwerke, chemische Reaktoren oder für die Wasserstoffproduktion durch Thermolyse von Wasser. Ein wichtiges Forschungsthema ist die Wechselwirkung von Wasserstoff mit diesen Materialien.
 

Methoden der Forschung

Die Forschung der Gruppe Atomistic Modeling and (experimental) Validation (aMeV) konzentriert sich auf die Entwicklung von Modellen zur Voraussage makroskopischer Materialeigenschaften auf Grundlage von Prozessen auf atomarer Ebene. Diese Herausforderung verlangt Multiskalenansätze, weshalb wir zu diesem Zweck verschiedene Methoden anwenden und die entwickelten theoretischen Modelle durch gezielte Experimente sorgfältig validieren.

Simulationsmethoden

Die folgenden Modellierungsmethoden werden von unserer Gruppe auf verschiedenen Raum- und Zeitskalen angewandt: 
•    Methoden der Dichtefunktionaltheorie (ab-initio),
•    konventionelle und auf der Dichtefunktionaltheorie basierende Molekulardynamik,
•    atomistische, gitterbasierte kinetische Monte Carlo Simulationen und Methoden der Ratengleichungen.

Wir verwenden Dichtefunktionaltheorie-Codes wie VASP, Fleur und Wien2k. Für Simulationen auf größeren zeitlichen und räumlichen Skalen werden die Molekulardynamik-Codes LAMMPS und PARCAS verwendet.
Wir verwenden überlicherweise Pymatgen und Atomate zur Automatisierung und Analyse der Big Data-artigen Resultate, die durch Hochdurchsatz-ab initio-Berechnungen erzeugt werden. Wir verbessern Methoden gegebenenfalls (z.B. die Climbing-String-, sowie Nudged-Elastic-Band- und Dimer-Methoden für die Suche nach Übergangszuständen wie im VTST-Paket implementiert) und reichen, falls angemessen, pull requests der Verbesserungen ein. Wir entwickeln Methoden zur Anwendung von maschinellem Lernen bei der Entwicklung interatomarer Interaktionspotentiale auf Grundlage der Ergebnisse von ab initio-Berechnungen.

Experimentalarbeit

Der experimentelle Teil unserer Gruppe arbeitet entlang drei Hauptrichtungen: 
•    Entwicklung und Charakterisierung von Beryllium und Be-Legierungen zur Anwendung in Mänteln zukünftiger Fusionsreaktoren;
•    Validierungsexperimente zur Verifizierung der vorgeschlagenen Modelle.
•    Untersuchung von Wasserstoffisotopenwechselwirkungen mit Metalloberflächen zur Validierung der Multiskalenmodelle des Desorptions-, Rückhalte- und Absorptionsverhaltens.
